英文摘要First-principles calculations are performed in this work to study the effects of M (M=Mg, Sr, Ba, La) substitution in CaB6. Both electronic structure and mechanical properties are examined. The current results indicate that the substitution of Ca by M atoms causes the lattice constants to scale linearly with the variation of x. The shear moduli of MxCa1-xB6 are found to be related to the valence d-electron Mulliken charges in the lattice. The hardnesses of M (M=Mg, Ca, Sr, Ba, La)B-6 and their solid solution are calculated by analyzing the overlap populations of the B-B bonds in the solid solution system.
